Next Generation Cummins 6.7 Liter Turbo Diesel is First to Deliver 1,000 Pound-Feet of Torque

DETROIT--(BUSINESS WIRE)--Jan. 14, 2019--
Cummins Inc. (NYSE: CMI) unveiled its next generation 6.7L turbo diesel
engine boasting a first-in-class 1,000 pound-feet of torque. In addition
to an increase in torque, the engine also has a higher horsepower output
taking the 2500 and 3500 heavy-duty RAM pickup truck customers to the
next level of performance.

“The Cummins name has been synonymous with technological innovation and
reliability since 1919,” said Melina Kennedy, General Manager – Cummins
Pickup segment. “We’re proud to introduce our most powerful 6.7L engine
ever on the year of our centennial – setting the new standard in the
heavy-duty pickup market.”

“In addition to celebrating 100 years of diesel engine production, we
are also celebrating 30 years of powering RAM trucks,” stated Srikanth
Padmanabhan, Vice President - Cummins Engine Business. “Together, RAM
and Cummins have accomplished many milestones and technological
advances. From the time the first prototype truck was put together in
the 1980s to now, breaking the 1,000 pound-feet barrier together,
exemplifies the strength of our partnership.”

Customers can expect the same reliability and dependability they have
experienced since Cummins began powering RAM trucks in 1989. Base engine
improvements made to support the new higher output ratings of the
next-generation 6.7L engine include a compacted graphite iron engine
block that increases peak cylinder pressure capability, a new cast-iron
cylinder head containing high-temperature capable exhaust valves
actuated by all-new hydraulic lash adjusters in the block eliminating
the need for valvetrain adjustment service intervals. The heart of the
engine is a higher strength alloy crankshaft with a 10-bolt crank flange
driving newly-designed forged connecting rods and new bearings, which
transfer power from the low-friction ring wrapped pistons.

A new larger Cummins-Holset variable-geometry turbocharger optimized
with heavy duty bearings, and a new compressor-side housing is a key
ingredient in the new ratings pumping 33 pounds per square inch (psi) of
fresh air into the engine.

The new fuel-delivery system includes a new 29,000 psi (2,000 bar) fuel
pump and fuel rail with Cummins Filtration “filter in filter” NanoNet®
technology.

In addition to displaying the most advanced and reliable RAM 2500 and
3500 heavy-duty engines, Cummins also displayed a 2.8L turbo diesel
engine alongside the latest turbocharging, filtration, and light-duty
aftertreatment technology.
